Smart man. Frames are ridiculously easy to build from scratch, especially if "cool" factor is not a criteria.
I love working with cedar, it's very light and plenty strong. I rip down a 2x4 and have plenty of material to build with for just pennies.

Hi,
someone asked for an onboard video, so here it is: just a short fun flight with some friends at a dry lake used by ultralight and rc planes...

Fold-A-Copter flight on board video (2 min 49 sec)

Add yours with a description / photos / video or a link to your topic.


I start with my first rc build from scratch.

A central plate of wood 40 cm x 10 cm x 1 cm.
Two arms 40cm x 2.5 cm x 1.5 cm
47 cm between the motors (diagonal)
=260g

openpilot CC3D
NTM 28-26A 1200kv & Series Accessory Pack
ESC 30A Flashed with SimonK FW from opstore.eu
8"x4.5 Carbon reinforced AP Propeller from flyduino.net
Gopro HD2 - Turnigy 9x - DragonLink
2200mAh 3S 25C Lipo (nano-tech or zippy compact)

AUW: 1300g
Autonomy: about 7 minutes.
have you run those motors on 4s? im loaded with 4s batts and only have a handful of 3s', would i be better off with the 1000kv versions on 4s with an 8x4.5 or 9050?
super keen to get a wooden H off the ground as an FPV ship in the next week or two.

The torsional strenght is preserved and it's easier to assemble
Thats a great design! . I am building a frame very similar to your frame and used 1.5mm fibreglass board.

Can you please tell me the weight of your frame as it is in the photo. I'm just wondering what weight I Should be aiming for.

Thank you topgun308
the bare frame tips the scale at about 350gr/12oz, it's not feather light but it's a good compromise for its robustness

Thank you for the reply, my frame is close to this weight.

For the fibreglass board I used single sided printed circuit board and etched away the copper cladding. This has saved a lot of weight and also drilling the aluminium arms saved some.

I'll post a photo when it's assembled again.

Yes it will work great with 4s and 8x4.5... more "aggressive"
Have you flight your H?

For me I have now 2 QuadH... yes FPV and H addict
for replacement in case of crash... narrowly averted on this last flight at 2:18

QuadH Sharing FPV (4 min 59 sec)

Great vid eyesonsky!! That thing has some serious forward moment going on!
Prefect flying area too,

No, flew my H briefly to test it out but it was a bit too heavy so moved to the spider style alu quad instead(see scratch built thread),
Would like to do another one but make the coffin body from 3mm ply instead of the 6mm that I had last time, get the weight down.

You're inspiring me to get it done though .
Good work.

Designing my first H frame... well, not that much to design, just to come up with right set of dimensions for particular use. Here is my current vision. Planning on using 10-11" props and 750kv motors. Naturally it will have fiberglass top plate but other than that, is that motor to motor distance (442 mm) good or...? Feedback please.

Industrial-Grade FPV H-Quad


Here's a few photos of my friend's industrial grade FPV H-Quad that he's building.

It's a tank, not a quad!

Not sure that is the best way to mount the KK board....
